To alllwhomiz' may concern.' v

Befitknoivn that I, ROBERT GOLDEN, eltizen o'fQthefUnited States, residing at Meehan Junctiomjn the county of Lauderdale and Stateoflllississippi, have invented new and useful Improvements in Transmission- Greari'ngof which the following is a specification." i

i present invention pertains to transthe machine is. traveling .over a ha d smooth for the equaliaing; transmission,gearing to` operate in the ordinary well known mannerfgf .,lVilhthe foregoing in mind, the invention v-qillbe `fully understood from the followingdescription and claims when the same'areread in connection with the ,drawings,`v accompanying and 'forming part of this specification, in which:

i Figure@ is a plan` lview illustrative of a gear. Iasing' containing my improvement,

and also. illustrative of the controllingv meanslprefer to employ. Fig. 2 is an enlargedeievation showing the transmission gearing constructed in accordance with my invention. F isa broken elevation showing the housing section contained in Fig. 2 as removed. F el: is a. view', partly in dianletrical section and partly in elevation, of the gearing constructed in accordance with my invention.v .Fig. is a detail view show ing the relative arrangement of one of the beveled pinions, its spindle, the adjusting ring, and the key complementary to the pinion and spindle. Fig. 6 is an elevation showing theouter side of one of the pinions. Fig. 7 is a perspective of one of the keys.

Similar numerals oi reference designate corresponding parts in all of the views of the drawings.

prises the usual beveled gear 1 for connection tothe axle of one traction Wheel, and the usual beveled gear 2 for connection t0 the axle of the other traction Wheel. Fixed vwith respect to a gear Wheel 3 that derives motion from the motor of the vehicle, and extending laterally yinward therefrom is an annular iange 4. The usual central sleeve 5 that is fixed with respect to the` beveled gear 2 is employed, and extending between and fixed to aboss 3a and the iiange Il are four (more or less) spindles or arbors 5 on which are loosely mounted beveled pinions 7 that are interposed betiveenand. intermeshed ivith the beveled gears 1 and 2. At this point attention is directed to the fact that whenthepinions 7 are loose or free to turn on the spindles G, the equalizing transmission gearing is adapted to operate in the ordinary Well-known manner. llfhen, however, the pinions 7 are keyed or locked to their respective spindles 6,v 'as hereinafterdescribed, the axles complementary Atov the gears 1 and 2 will be locked. together, and on turning of the Wheel 3 the traction wheels on both of said axles vvill be positively driven as if they were in one piece. As clearly appears in Fig. el, lthe gear 312s loose on the exteriorly-circular lsleeve 5 ot the gear 2. A

In furtherance of my invention, I provid the housing section S of the gearing with ribs 9 and key-receiving recesses 10.A Also in furtherance of the presentinvention,

notches 11 are provided in the interposed pinions, andkey-receiving recesses 12 are provided in the spindlesor arbors, which recesses 12 are interseeted by pins 13 arranged transversely of the spindles or arbors. i

Arranged in the key-receivingy recessesV 10 of the housing section 8, and also in the keyreceiving recesses 12 of the arbors or spindles, are keys 14. These keys are slotted to receive rollers 15 on the pins 13, and are designed to be moved into thelnotches 11 of the .pinions to lock the pinions to the spindles jor arbors, and out of said notches 4to renderl the 'pinions loose on the spindles or arbore, for the purposes hereinbefore set forth. lt will be manifest by reference to the drawings that each key 14C is provided at its outer end With T-head 16, and that the said head is inclined in the direction of the length thereof. ,The pins 13 'and rollers lmanifestly constitute fas that receive the ribs 9, notches 22 that re- 21 isy moved toward the wheel 3, the keys 1 known operation of the gearing.

rtu

`end portions of the keys will be'drawn out teners for holding the keys 14 in the spindles 6. f

-Guided on the ribs 9 ofthe housing section 8 and loosely surrounding the circular flange on the wheel 3, and mbvable laterally toward and from the, side of the said wheel is av circumferentially-grooved ring 21. This' ring 21 is provided with notches 22a ceive'the radiallydisposed portions of the' keys, and inclined cam grooves 23 that receive the inclined heads of the keys. Gonsequently when the 'ring 21 is moved ina direction away from the wheel 3, the inner of the pinions to render the pinions loose on the spindles or arbors, while when the ring will-be moved endwise inwardly into the notches of the pinions to lock the pinions to the spindles or arbor's and lock t e beveled gears land 2 to eachother. In the first pof sition of the keys, the gearing is adapted to operate in the ordinary wel known man-4 ner, while in the second position of the keys the two axles are secured together and willl turn as one piece. It will also be manifest that when the ring2l is held by any ap proved means in its, position away-from the wheel 3, there is no liability of the keys interfering with the rot-ation of the pinions about their spindles and the ordinary well Any suitable means may be employed for enabling the automobile operator to moveI` and control the ring 21.` .1' refer,however, to employ "the rod 31 guide in the gear casing and having a curvilinear portion 32 seated in the circumferential groove of the ring, a suitably supportedlbell-crank .3B having one of its arms connected to the outer portion oi. the rod 31, 'and a rod Bs'extending forwardly from the other armfof the bell-crank and connected to a' lever 35, dis posed adjacent the seat of the automobile operator. r f

Having described my invention, What-.I claim and desire to secure oy Letters'Patent` L. The combination with opposed gears, a wheel adapted to berotated, pinions interposed between said gears, and spindles carried by said wheel, on which said pinions are loosely mounted,-said pinions having' interior notches `and said spindles having recesses and key-fasteners therein; of keys mounted insaid recesses and on said fasteners and having inner end portions movable and a laterally-movable ring surrounding .the keys and having notches receiving the.

radially-disposed portions of the keys-.and also having inclined cam grooves vreceiving the T-heads of the keys.

2. The combination with opposed gears, a wheel adapted to be rotated, pinions interposed between said gearspand s indles can. ried by said Wheel, on which saidp inions are loosely mounted, said pinions aving interior notches rand'said spindles having recesses and 'key-fasteners therein; of keys mounted in said recesses and on saidfastoners and having inner end portions mo'v.-l able into and out of the pinion notches and also having inclined T-heads at their, outer ends, a laterally-movable circumferentiallygrooved ring surrounding. the keysand hav:

ing notches receiving the' radially-disposed.

portions ofthe keys and also havin inclined' cam-grooves recelving. 'the T-hea s of the keys', an endwise movable rod having .a vpor-.- tion disposed in the circumferential groove of the ring, andmeans for moving. said rod.

3. .The combination with' opposed gears, a wheely adapted to be rotated, pinions interposed between said gears, and spindles'car ried-by said wheel, on which said pinions are' loosely mounted, of keysconstructed and arranged in one `position to lock the pinions to said spindles,and in another'v position to render the pinions loose on the spindles, and meansfor moving the keys from one position tothe other and -vice versa. f Il. The 'combination with a transmission gearing comprising opposed beveled gears, a wheel loose with respect4 to said gearsand adapted to be connected with a motor andl having a lateral annulary ange, recessed spindles connected with said ilange, inte,

riorly notched pinions loosely mounted on said spindles, vand a housing section connected to saidl'lange and having key-receive ing recesses-and also having exterior guide ribs; of a laterally-movable flange guided on said ribs and having notches in its inner side and inclined camA recesses communicating with said notches, andfe'ndwise-mov-v able {eys arranged in the key-receiving recesses of the spindles and housing section and extending through the notches in the ring and having inclined T-heads disposed in the inclined cam recesses of the ring.
